Small games with a big X and O energy.
Outmark is a home for short games of X and O. Each one takes a rule you have known since childhood and bends it: keep only six marks, slide the whole board, play tricks, tie every move to the last. Every game has a new puzzle every day, bots to beat, and a link you can send a friend.
The games
More are on the way. Each new game joins your streak, your bot record and your friend links on its own.
How it works
- Free to play
- Every game, every mode, every day. No download, and no account unless you want your progress on more than one device.
- Made independently
- Outmark is built and run by one independent developer, not a studio. Ideas and bug reports go straight to the person who fixes them.
- Fair to your time
- No energy meters, no loot boxes, nothing that holds a game back until you pay. A short ad may play between games, never during a turn.
- Light on data
- Your progress lives on your device. We count anonymous daily totals so we know which games people enjoy. Details are in the privacy policy.
Keep Outmark going
If Outmark has become part of your day, the Supporter pass is the best way to help. It is one payment, not a subscription, and it pays for the servers and the next game.
- Ad-free play in every Outmark game
- Supporter palettes for the boards
- Works on every device you sign in on
The Supporter pass opens soon. Playing and sharing Outmark helps just as much for now.
